Pentagon spokesman George Little said the drone displayed by the Revolutionary Guards on Tuesday appeared to be a U.S.-made ScanEagle. He said it could not be determined if the drone was operated by the US.

Commenting on Tehran's claims that it extracted valuable data from the ScanEagle, reportedly captured in the Persian Gulf, Little said it was “highly improbable” that useful intelligence could be gained from the relatively unsophisticated drone.

Iran News Network claims that two former Ministers have asked for a staff from the Executive, legislative, and judicial branches to be organised to manage the country, effectively taking power from the Government.

Radio Farda suggests the two ex-Ministers could be Iran Inspector General and former Minister of Interior Mostafa Pourmohammadi and former Foreign Minister Manouchehr Mottaki.

Today Robert Tait of The Daily Telegraph of London adds a third name and the claim that the appeal was made to Ayatollah Khamenei:

Three of Mahmoud Ahmadinejad's former ministers have called on Iran's supreme leader to form an emergency "government of all the talents" that will effectively curb the president's power.

Manouchehr Mottaki, the former foreign minister, Mostafa Pourmohammadi, who served as interior minister, and Davoud Danesh Jafari, the ex-finance minister, have urged the radical move in a letter to Ayatollah Ali Khamenei, citing the country's "sensitive and critical situation".

It calls for the establishment of a special cabinet of "wise men" made up of the heads of the executive, legislative and judicial branches, which would then govern Iran for the next year until Mr Ahmadinejad's term ends.

Mr Ahmadinejad would be a member of such a body as head of the executive branch. But his powers would be diluted and prestige drastically reduced....

In an editorial, [pro-Ahmadinejad newspaper] Iran criticised the former ministers' note as an attempt "to portray the country's situation as critical and justify extraordinary approaches outside legal boundaries to resolve an artificial crisis".

Azumi had said Thursday, after talks with US Secretary of Treasury Tim Geithner, that Japan would reduce oil imports but Noda said today that the Government has yet to decide because businesses implications need to be considered. He described Azumi's remarks as a "personal view".

Noda continued, "Japan's basic stance is to resolve such matters diplomatically and peacefully. We need to consult with the business community, and we need to work out details with U.S. officials. We have to think about the implications for Japanese banks, and what measures are needed to resolve possible negative impact."

1941 GMT: The Terrorist Plot. We have just posted the US Department of Justice press release summarising the alleged plot, backed by elements of the Revolutionary Guards, to kill the Saudi Ambassador to Washington.

We have also posted a copy of the original complaint filed in the Court of the Southern District of New York.

Attorney General Eric Holder, when asked how Iran would be held "accountable" in an alleged plot to assassinate the Saudi ambassador to the United States, said he expected action from the White House, the State Department and Treasury within the next few hours.

A US official expanded more about how the U.S. might hold Iran accountable. The official told CNN's Elise Labott that there are likely to be more sanctions and the U.S. will be taking this up with to the United Nations Security Council and other members of the international community.

1710 GMT: Political Prisoner Watch. A friend of physician and blogger Mehdi Khazali has given an account of the arrest after Khazali was summoned to the Ministry of Intelligence on Monday:

When Dr. Khazali arrived at the Intelligence Ministry they presented him with an arrest warrant. Dr. Khazali told them this warrant is 10 days old and he already posted bond for it four days ago.

The agent replied that he has to arrest him and the Court’s instructions don’t mean anything to him. Dr. Khazali told him this warrant is illegal and I won't go with you.

All of a sudden three people jumped on him and throw him to the ground and handcuffed him. They placed him in a car, positioned him laying down with one agent sitting on his neck and one sitting on his stomach as his teenaged son was watching in shock.

The friend was also in court when Khazali was arraigned on Tuesday:

After they brought the doctor in, I was shocked, he was in prison attire, handcuffed and shackled, with his bruised swollen neck bent to one side and accompanied by two agents on each side.

1150 GMT: Revolutionary Guards Do Politics. Ayatollah Alamolhoda, the Friday Prayer leader of Mashhad, tries to clarify the issue of whether the Islamic Revolutionary Guards Corps can intervene in political issues --- he explains that the late Ayatollah Khomeini never said the IRGC should not enter politics, only that they should not interfere in political parties and elections.

IRGC commander Hossein Hamedani offers another bit of logic to support the Revolutionary Guards' invovlement: all Iranian people are Basiji fighting for the country, the Revolutionary Guards are not separated from the Basij, thus the IRGC is a principlist movement beyond a narrow military role.
